Using an SS Shimano RD with 11/28?
Hello, I've ordered by mistake the Shimano 105 rear derailleur SS, thinking that GS was meant only for triple crank, and I've ordered also a 11/28 Dura-Ace casette and a 50/34 105 crank. I guess it will be impossible to use 50-28, but the next casette cog is 24, that would be a wrap of 16 crank + 13 casette = 29, that is precisely the SS maximum wrap. Would be possible to use this gear (50x24) and not to return it to the shop? Many thanks.
